The Traffic Light Block is very useful to manage traffic in bigger systems where paths of vehicles might cross eachother!

First of all you need a path where you can add the traffic light.
For this guide I have chosen this path where the direction is from left to right and I want to add a traffic light at the third Street Node.
At the right side are just three Address Nodes for testing.

1) Add the Traffic Light Block
2) Connect an input to the Traffic Light Block
NOTE: This is just a button with some logic gates to shorten the signal
3) [Optional] Hide everything under the road and add a 'real' traffic light
NOTE: To get the output of the block you can just connect the light / a gate to the block. Also to get the 'green signal' just connect a nor gate to the Traffic Light Block and connect it to the green light

RESULT: You have a traffic light that will stop the comming vehicles when they are close enought

I hope this guide was helpful! If you have suggestions on how to improve the mod or this guide let me know :)
